Paper Abstract

The analysis of the RX concentrator as an imaging optical system is presented. When the field of view is small (less than 6 degrees full angle), even for concentrations up to 95% of the theoretical maximum, its imaging performance is similar (in MTF terms) to that for normal incidence of an f/3.7 planoconvex spherical lens with optimum defocusing. This imaging capability allows us to use the same RXc with receivers/emitters different from the one of design with no loss of nonimaging quality. Also this feature combined with its capability to concentrate radiation close to the thermodynamical upper bound suggest that the RXc may be an interesting optical device for focal plane array applications.
